The Human Body: Systems and Survival

A comprehensive journey through human anatomy and physiology, designed for the aspiring medical professional. Learn how the body maintains balance, responds to stress, and functions as a complex biological machine.

Like Duolingo, but for The Human Body: Systems and Survival. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

87 levels across 8 sections, about 174 minutes end to end, roughly 35 days at five minutes a day. It moves through The Body's Dashboard, The Biological Foundation, The Framework of Motion, The Information Highway, The Transport System, The Energy Exchange, The Filtration Plant, and The Whole Organism. It starts from scratch.
